CASK.

SPECIFICATION forming part of `Letters Patent No. 276,364, dated April 24, 1883. Application tiled February 16, 1883. (No model.)

Be it known that I, CHARLES L. GRUM, of Winchester, in the county of Frederick and State of Virginia, have invented a new and uset'ul Improvementin Oasks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will en-` able others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciication, in Which- Figure l is a sectional view taken through thecask lengthwise. Fig. 2 is a cross-section taken through the dotted line a: a' ot Fig. 1, and Fig. 3 shows a horizontal section of one ot'- the segments ofthe cask. e

This invention has for its object the production ot' a cask from the ordinary straw or other pulp board in such form as can be .knocked down or `taken to pieces for transportation and then put together with little labor and expense. It is also of such shape as will make it as easily handled as the ordinary wooden eask.

I first take the straw or other pulp board as it comes from the machine upon which it is made and cut it into proper shape. I pass the sheets through a hot substance or composition to make it in a degree water and acid proof'.Y I then subject the separate sheets to heavy pressure by means of rolls or dies ot' such form as will give the sheets the proper curvature. `I then unite as many of the sheets as may be necessary to form sheets of due strength. For this purpose I use a water-proof glue or paste. `I again subject the united sheets to pressure in the rolls or dies, so that they will retain theirproper form as segments of the body ot' the casks. I then unite, with glue or other adhesive substance, or rivets, as many ofthe segments as may be necessary to make the sides of the eask the desired thickness and strength, allowing the edge of each alternate layer to project a suiieient distance beyond the layers adjoining it toform tongues on one side and grooves on the other, so that when the sections are put together the overlapping sheets will form a tight and substantial join t. It' the caskis to be used I'orliquids, a water-proof cement must be used in the joints,

land, as a further security, the joints can be riveted together. The heads are formed by building up the desired thickness with sheets of board rst subjected to the hot waterproof'- ing solution, and glued and pressed together.

The drawings represent acask, made of-three thicknesses of boards, andthe cylinder or body of the cask made into three segments.

a represents the cylinder or bodyof thecask; b b', the heads; c c', the head-hoops. c2 c3 are the quarter or bulgehoops, which maybe made ot' wood, metal, or paper. d d represent wooden or paper hoops or boards, secured to theinside ot' the cylinder, near the upper and lower ends of the cask, for the heads to rest upon. In ordinary casks the curvature of the ends ot' the cylinder will be sufficientto hold the heads in place; but for tight casks I also may secure the heads by grooves or crozes on the inside ofthe cylinder and form the edge ot' the heads to correspond with and fit into the grooves.`

When the casks are intended for acetic substances the inside sheets may be liirst saturated or coated with parafline or any like sub" stance. Y

I do not confine myself to the number oflayers or thickness ofthe material used. Neither do I confine myself to the number of segments into which the body of the cask is divided. Casks for different uses will require different modifications. n

Having thus described my invention, what I claim as new is- 1. Asegment of a cask made of paper-board and consisting of a series ot' layers united together, each alternate layer projecting beyond the layers adjoining it at one end ot' the segment, substantially as shown and described, whereby a tongue is formed at one end of the segment and a groove at its opposite end, as set forth.

2. A cask made of segments constructed of layers/otypapenboard arrau ged, as set forth, to form tongues and grooves at their opposite ends, substantially as described.
